About PeptaPeptides

Built by Researchers,
For Researchers.

PeptaPeptides exists because we were tired of ordering compounds that didn't live up to their purity claims. So we built the supplier we always wished existed — one that treats analytical rigor as a baseline, not a selling point.

Our Mission

We exist to make research-grade peptide compounds accessible, reliable, and completely transparent. Every order we ship comes with the documentation you need to trust it — not because we have to, but because that's the standard science deserves.

We serve university laboratories, independent researchers, and biotech organizations who need compounds they can stake their results on. We don't ship anything we wouldn't use in our own research — and we have the CoAs to prove it.

What We Do

  • Synthesize and supply research-grade peptide compounds
  • Independently verify every batch with third-party HPLC and MS analysis
  • Provide lot-specific Certificates of Analysis on every order
  • Ship with full cold-chain integrity — dry ice, insulated packaging, temperature indicators
  • Deliver to 50+ countries with proper documentation for research importation
  • Provide PhD-level scientific support to researchers who need it

What We Stand For

Six principles that guide every synthesis, every shipment, and every support response.

Uncompromising Purity

We hold every batch to 99%+ purity. If it doesn't pass, it doesn't ship. No exceptions, no "close enough."

Independent Verification

Every lot undergoes third-party HPLC and mass-spec analysis. Our Certificates of Analysis are lot-specific — not templates.

Scientific Expertise

Our team includes PhD-level chemists and research biochemists who designed the synthesis protocols we use every single day.

Cold-Chain Integrity

Lyophilized compounds are packed with dry ice and temperature indicators. Your compound arrives in the same condition it left our lab.

Global Reach

We ship to 50+ countries and understand the documentation requirements for research compound importation across major scientific markets.

Researcher-First Support

When you have a question, you talk to someone who understands the science — not a script. Our support team is staffed by researchers, for researchers.
